Conection refused error error when run oss-performance on HHVM.

[racardoso]

I'm trying to run oss-performance (with siege 2.78) on HHVM 3.13 (installed from package) with nginx and fastcgi on x86-64 machine with Ubuntu 15.04. Works fine for toys-helloworld, toys-fibonacci and, wordpress but, fails on sanity check for the others benchmarks (laravel, magento, mediwiki, drupal).

Example:
Running mediawiki: hhvm perf.php --mediawiki --hhvm=/usr/bin/hhvm

Warning: failed to connect to localhost [111]: Connection refused in /home/rcardoso/oss-performance/base/SystemChecks.php on line 83

I have the same problem cloning from master and install it from package (HHVM 3.13). After that i clone HHVM-3.11 tag in the same machine, with the same configuration and mediawiki (and the others tests) runs fine (that exclude some obvious configuration error). The problem seems to occur on versions 3.12 and 3.13.

Appears to be related with task #6764 . Added assert.active=false on php.ini file solves the problem. A pull request will be opened to oss-performance.
